Area Forecast Discussion National Weather Service San Diego CA 804 PM PST Fri Jan 17 2020

SYNOPSIS. Fair and warmer weather is forecast through the weekend with higher pressure aloft and some offshore flow. Cooler weather will return next week with lower pressure moving through the region. There is a slight chance of showers Tuesday and Wednesday and it could get windy in mountains and deserts.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

Skies have cleared this evening, except for some wispy high clouds drifting by. Some offshore flow has generated some breezes in the foothills, some gusting 20-30 mph. Offshore pressure gradients have begun to align and tighten up, so we expect areas of offshore breezes of similar strength to contine through the weekend, mainly in these foothills and adjacent inland valleys. High pressure tries to build aloft and that should bring a modest warming trend; Sunday looks like the warmest day in the coming week. Skies will show occasional high clouds and probably no low clouds. Guidance shows a gradual breakdown in our weak ridge, turning slowly into a weak trough situation Monday through Wednesday. That should increase our onshore flow and bring back some coastal low clouds, but also some brisk onshore winds for mountains and adjacent deserts. Moisture increases a little at the same time, leading to our underwhelming slight chance of precipitation Tuesday into Wednesday. That's a forecast that's bound to get adjusted a few times in the meantime. Cool, cloudier and brisk is a good bet even if rain isn't. Thursday and Friday look fair and warmer under a tepid ridge of high pressure. The jet stream just isn't favorably pointed at SoCal lately and won't be for a while. There are hints that some fast-moving shortwave trough could undercut the ridge at some point to give us precip, but nothing showing promise at the moment. Look for cool nights and warm days with temperatures close to average for this time of year.

AVIATION. 180330Z . There's high confidence in VFR conditions persisting at all terminals into Saturday night. SCT-BKN high clouds AOA 20,000 FT MSL are expected through the period. Winds will remain light, with only a weak onshore breeze at coastal TAF sites during the afternoon hours on Saturday.

MARINE. No hazardous marine weather is expected through Tuesday. Some increase in wave heights is likely on Wednesday with new NW swell, with seas of 7-10 FT possible over extreme southwestern portions of the outer waters south of San Clemente Island.

SKYWARN. Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.

SGX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
